Fire-retarding composition for fabric of special purpose of moleskine type based on aflammit-sap and silicon dioxide

FIELD: chemistry.

SUBSTANCE: wide practical use for fire-proof finishing of cellulose-containing tissues of special purpose, including Moleskine (dense and strong cotton fabric produced by reinforced sateen weave), found flame retardants based on organic nitrogen-phosphorus compounds. Aflammit SAP - Tetrakis(oxymethyl)phosphonium chloride (hereinafter TPC) relates to compounds of this kind. However, at present moment there is a problem of TPC are on woven material. Existing technology of finishing Aflammit SAP fabric has some shortcomings: 1. Large number of steps and labour intensity of process of application and fixation. 2. High environmental risk and fire and explosion hazard (ammonia, its dangerous action in case of accident, in production, in recycling). 3. Reduced tensile strength. Disclosed is a method of applying commercial antipyrrite preparation "Aflammit SAP" on Moleskine, alternative multistep, fire-explosion- and environmentally hazardous industrial method. In disclosed fixation of Aflammit SAP on fabric surface is carried out without using ammonia, but using a solution of 1,4-dibromobutane in non-aqueous solvent. Technology of application Aflammit SAP on Moleskine 1. Before application of fire-retardant composition tissue samples are held for 72 hours in water, changing said water every 24 hours. 2. Drying samples. 3. Treating with hot steam. 4. Application of anti-pyrrhite composition based on aqueous solution of Aflammit SAP (600 g of preparation of Tetrakis(oxymethyl)phosphonium chloride (Aflammit SAP) in 1,000 g H2O) on samples of moleskine by padding method. 5. Heat fixing composition at temperature 150 C for 15 minutes. 6. Application of fabric samples 9.22 % solution of 1,4-dibrombutane in carbon tetrachloride with addition of 3.5 wt% silicon dioxide (commercial preparation "Kovelos"). 7. Atmospheric drying of treated samples.

EFFECT: wide practical use for fire-proof finishing of cellulose-containing fabric of special purpose.

SUBSTANCE: invention can be used in the textile industry for production of antimicrobial argentiferous cellulosic materials. The method of production of antimicrobial argentiferous cellulosic material comprises processing of the cellulose matrix by the aqueous dispersion of the silver particles for 10-60 sec, obtained by mixing an alkali extract of bast fibres with an aqueous solution of silver nitrate and keeping this mixture at a temperature of 50-95C for 10-90 min.

EFFECT: invention enables to reduce loss of the active components, to reduce the time and energy consumption during production of antimicrobial materials and also to improve the quality of the processed nonwoven material and environmental safety.

SUBSTANCE: invention relates to technology of production of antimicrobial copper-containing cellulose materials and can be used in the textile industry. A cellulose matrix is processed with water dispersion of copper particles with their concentration of 0.025-1.28 wt %. Dispersion is obtained by mixing an alkaline extract of bast fibres with a copper salt solution and with a reductant solution and standing of the said mixture at a temperature from room to 95C for 10-60 min. A concentration of the alkaline extract of the bast fibres in the dispersion constitutes 10-80 wt %. Processing the cellulose material with water dispersion of copper particles is carried out by impregnation or aerosol application. As the reductant used are taken separately or in a combination with each other compounds, selected from the group of reductants, capable of reducing copper ions, for instance, sodium borohydride, rongalite, sodium thiosulphate, hydrazine sulphate. As the copper salt, copper sulphate, chloride, acetate or nitrate is used. In obtaining water dispersion of copper particles a ratio of the reductant and the copper salt concentrations constitutes 1:1-1:2.5.

EFFECT: application of the invention makes it possible to increase efficiency of obtaining the antimicrobial copper-containing cellulose material, quality of processed the non-woven material and ecological safety.

SUBSTANCE: along the slot there is a through-hole for connection pipe interconnected with slot with diameter larger than connection pipe diameter. The connection pipe has longitudinal slotted hole and arranged in such a way that longitudinal slotted hole is diametrically opposite the tank slot (slots). At the face ends of longitudinal slotted hole there are mounted shut-off glands tightly contacting the walls of tank through-hole. One end of connection pipe is equipped with fitting for binding substance supply in it, the other is plugged or also equipped with fitting for binding substance supply in it, note that connection pipe casing and the internal surface of through-hole for it form two channels limited by shut-off glands for binding substance passing. In case there are two slots in the tank the latter have equal width and are located with shift, and if there are not less than three slots in the tank, the latter also have equal width and are arranged in staggered order. There are heating elements installed on tank housing.
